Answer:

Explanation:

The estimate value of 1.68,

→ 17 ≈ 17

→ 17 × 2 = 34

Therefore, the product is 34.

Answer:

34

Explanation:

When estimating the product of an integer and a decimal, first round the decimal to its nearest whole number.

  • If the digit in the tenth place is less than 5, round down to the nearest whole number.
  • If the digit in the tenth place is 5 or more, round up to the nearest whole number.

Therefore,

  • 1.68 ≈ 2

So an estimate of the product is:


\implies 17 * 1.68 \approx 17 * 2

Partition 17 into tens and units:


\implies17 * 2= (10+7) * 2

Apply the distributive property of multiplication over addition:


\begin{aligned}\implies (10+7) * 2&=(10 * 2)+(7 * 2)\\&=20+14\\&=34\end{aligned}

Therefore:


\boxed{17 * 1.68 \approx 34}
